This is what I've done: There were these little starfishs who rang our doorbell at 3:00 in the morning. Now we have a little "zen garden" that is full of bushes and trees that you can hide behind. I put those explosive garbanzo beans(spelling?)under our welcome mat and I hid in the bushes. When they came to ring our doorbell they were startled, so I shot them with my BB pistol and egged them. They never rang our doorbell ever again, and when I see them, they always have a little twinkle of fear in their eyes......
